The advert shows an ‘everyday’ man walking through a variety of locations, including a café, pub, garage and office, which will all be required to be smoke-free.

The character explains that from 1 July, smoking will no longer be allowed in enclosed and substantially enclosed public places and workplaces. The ad finishes outdoors, in a pub garden, where smoking will be permitted.

Recent research carried out among businesses in England showed that 41% did not realise that smoking rooms will have to be closed. More than half were unaware that work vehicles will also be covered by the legislation.

A government survey of 1,700 adults found that 36% cited a smoke-filled atmosphere as the main turn-off for going to a bar or pub.

Public health minister Caroline Flint said: “The campaign is a reminder to people of the date [of the smoking ban] and gives examples of the range of locations which will be smoke-free. It forms part of a comprehensive communications campaign to make sure that businesses and individuals understand what action they need to take.”
